Snow Depth Map

I just found this interesting site which contains an interactive map regarding snow depth amounts. I don't know too much about it, but seems to at least have some potential for providing some useful information. You can request anything from current snow depth to 2 day snow fall totals. The 2 and 3-day snowfall maps don't appear to be very comprehensive or accurate. However, the other maps provide some interesting data in terms of current snowfall depths. You can zoom in and zoom out as well as pan all over the country.
